摘要：China’ s natural gas consumption has nearly doubled over the past five years. To better meet demand, China National Petroleum Corporation (CNPC), China’ s largest oil and natural gas producer and supplier, partnered with researchers from the University of California, Berkeley and Tsinghua University (Beijing) to apply innovative operations research to develop and implement new software that helps CNPC improve management of their gas pipeline network. Previously, all pipeline production and construction planning for CNPC, which controls 72 percent of the country’s natural gas resources and 70 percent of its pipeline network, was conducted by traditional methods using spreadsheets. However, the network’s increasing size and complexity caused the traditional method to permit excess costs and wasted resources. Since implementation at the end of 2014, the new software containing the three-stage convex relaxation method and iterative piecewise linear approximation methods enabled CNPC to realize approximately $530 million in profits. Moreover the resulting increased efficiency of the existing pipeline network made possible postponing the need for new pipelines, leading to an official budget reduction of over $20 billion in construction cost for the next five years.
